  def test(n: Int): Boolean = 
    {
    n % 3 == 0 || n % 7 == 0;
    }
     
   def main(args: Array[String]): Unit = {
      println("Result: " + test(3));
      println("Result: " + test(14));
      println("Result: " + test(12));

Previous: Write a Scala program to create a new string with the last char added at the front and back of a given string of length 1 or more.
Next: Write a Scala program to create a new string taking the first 3 characters of a given string and return the string with the 3 characters added at both the front and back. If the given string length is less than 3, use whatever characters are there.
